Application tiled July 24, 1917. Serial No. 182,453.

Blinds; and I do hereby declare the followdesignated by the numeral 3 and supported ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in window blinds an the principal object of the invention is to provide a window blind patterned after the ordinary Venetian blind which is arranged to be readily folded in its raised position and which is provided with guides fixed to the window casing in such a manner as to control the opening and closing of the blind.

Another object of the invention is to provide a blind consisting of a plurality of pivotally mounted slats or laths which are arranged'to be adjusted to various angles when the blind is in open or operative position so as to control'the amount of light admitted to a room.

Still another object of the invention is to provide a novel form of guide and controlling mechanism for the blind which may be readily attached to an ordinary window casing. Y

With these and other objects in view, the

invention. consists in the novel combination and arrangement of arts which will be fully set forth in the fol owing specification and accompanying drawings, in which Figure 1 is a face view of the blind constructed in accordance with this invention.

Fig. 2 is a-vertical enlarged scale taken on line 22 of Fig. 1 and showing the blind partly closed.

Fig. 3 is an enlarged fragmentary view showing the window casing and guide rods attached'thereto and showing the blind partiall lowered.

Flg. 4: is a view illustrating the position of-th blind when in'its raised position, and

. Fig. 5 is a detail perspective view of part of the connectingllinks of the device.

Referring to t e drawings, 1 designates a window casing of the ordinary construction provided with the usual vertical stiles 2 on which' the guide rails of the bhnd are mounted. The gu'de rails above referred to are Province of Ontario, Do-

. adjacent links sectional view on an in suitable brackets lat the upper and lower ends of the stile as will be clearly seen upon reference to Fig. 1. Mounted adjacent the guide rails 3 and spaced inwardly toward the center of the window therefrom for a short distance are the guide bars 5 which are provlded at their upper ends with the head 6 having the curved upper faces" 7 the use of which .will appear as the description proceeds. As shown in the drawings the upper ends of the guide rails 5 are positioned below the upper ends of the guide bars 3 and *the rails are positioned in a plane inwardly from the plane of the guide bars as clearly shown in Fig. 3. The lower ends of the guide rails are supported in the brackets 8 arranged adjacent the brackets 4: at the lower ends of the guide bars as will beclearly seen upon reference to Fig. 1.

Slidably mounted on the guide bars 3 are suitable eyes '9 provided with the shanks 10 which project through the central portion of the links 11 and into the ends of the slats or laths 12. It will thus be seen that the bars and may be adjusted to control the quantity of light admitted to or excluded from the room in which the device is used. The links 11 are.arranged when the curtain is lowered to engage against the guide rails 5 as illustrated in Figs. 2 and3 so that their lower ends contact with said rail while their upper ends are positioned against the next immediately thereover. The lower ends of the links are connected suitable connecting links 13 to the central portion' of the link immediately beneath the same as clearly illustrated in Fig. 5 and these links 13 are pivoted as shown at 14: to the lower end of the upper link and the lower ends of the links 13 are provided with openings 15 for the reception of the shanks-10 of the eyes 9. It will thus be seen that a train like structure is provided having the upper ends of its'alternate links extended to engage against the links immediately thereover when the blind is in its lowered position.

In order that the positions of the slats or so I wardly from the window casing as shown in Fig. 2 and this roller has wound thereon a flexible member 19 which is connected at its lower end to the bottom lath or slat 20 of the blind. A suitable controlling cord 20 is.

arranged to control the rotation of the roller 17 and a pulling cord 21 is connected to the bottom slat 22 by means of which the device is lowered.

It will be apparent from the foregoing that in use the blind is set up in the manner illustrated and when it is desired to lower the same pull is exerted on the cord- 22 until the blind is in the proper position. Should it be so desired it will be evident that the slats may be swung on their pivot to control the quantity of light admitted to the room and when it is desired to raise the same pull is exerted on the cord- 21 and it will be evident that the cord 19 will wind upon the roller 17 thereby moving the lower end of the blind upwardly and causing the links to 'fold in the manner shown in Fig. 2 until the slats are moved so their adjacent faces en-' gage each other as will be clearly seen upon reference to the figure above mentioned and in this way it will be seen that the blindmay be readily raised and lowered and will be held against blowing about by the wind due to the fact that it is slidably mounted on the guide rods 3.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement ofparts as will fall within thespirit and scope of the appended claims.

What is, claimed is 1. In a blind of the class described, a pair of guide bars attached to. the stiles of a window, slats positioned between the guide bars,

shanks extending longitudinally from the slats, and having eyes on the ends thereof which surround the ggiide bars to prevent the blind from being lown about, links on the shanks to facilitate in the foldin of the blind and means controlling the raising and lowering of the blind.

2. A blind comprising a pair of guide bars attached to the stiles of a window casing,

surrounding said guide bars, slats pivotally mounted on the adjacent ends of the shanks, links pivotally mounted on the shanks, guide rods attached to the stiles of the window immediately behind the links. and

casin forming bearings for the links, connecting links connecting the lower. ends of the first mentioned links with the links immediately beneath the same, means to move all of the slats simultaneously upon the movement of one of said slats and means eontrollingthe raising and lowering of the blind.

3. In a blind of the class described, a pair of guide rails secured to the stiles of a win and lowering of the blind.

4. A blind comprising a pair of guide rails attached to the stiles of a window casing, shanks havin eyes on one end which surround said guide rails, slats pivotally mounted on the adjacent ends of the shanks, links pivotally mounted on the shanks, guide bars attached to the stiles of the window casing immediately behind thelinks and forming bearings for the links to facilitate the raising and lowering of the blind by engagement with the slats, and means for raising and lowering the blind.
